| 摘 要： | 对比张集矿井2000年和2007年CBERS图像,计算归一化植被指数NDVI并结合目视判读和计算机非监督分类方法,提取矿区开采塌陷和新建工业广场、公路、铁路等空间要素信息。在ArcGIS9.0平台下从原始数据库中提取各种土地利用类型要素,分别与矿区开采塌陷要素进行叠加分析,得出开采塌陷影响各种类型土地范围和准确影响面积结果,并结合遥感图像,对原数据库内矢量要素进行匹配调整,完成对张集矿区GIS数据库的更新。

| Abstract: | The CBERS images of Zhangji mining area in 2000 and the images in 2007 are compared,and the spatial elements such as the mining subsided land and the new mining industrial square,roads and railways are extracted by the normalized difference vegetation index(NDVI) calculation and unsupervised classification.The newer spatial object data are saved into Zhangji mining area's GIS-based database on ArcGIS9.0.Overlay analyses between mining subsidence and original land-use elements are done in order to get the sc... |
